About Office Visit billing
Evaluation & management (E&M) codes for office visits are the most frequently billed codes in medicine. They are also a leading source of upcoding — where a provider bills a higher-complexity level than the visit actually supports.
Request the office visit note. Compare the documented history, exam, and medical decision-making against the 2021 AMA E&M guidelines. If the documentation doesn't support the billed level, request a downcode.
How to dispute a CPT 99213 overcharge
- Request the itemized bill. You are entitled to a detailed line-by-line bill showing every CPT code billed. Ask in writing.
- Compare to Medicare allowable. If the charge exceeds 150% of Medicare ($140), you have grounds to dispute.
- Request documentation. For E&M codes, ask for the visit note. For procedures, ask for the operative report. The documentation must justify the code billed.
- Send a formal dispute letter. Cite the specific discrepancy between the documentation and the code. Reference Medicare rates and NCCI edits where applicable.
- Follow up in writing. Give the provider 30 days to respond. If they don't, escalate to the state attorney general and insurance commissioner.
